CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 510,211, dated December5, 1893.

Application filed October 30, 1891. Serial No. 410,394. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH A. TREAT, a citizen of the United States,residing at Stuart, in the county of Guthrie and State of Iowa, haveinvented certain new and useful Improvements in Cash Registers andIndicators, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to new and useful improvements in cash registersand indicators, and the invention consists in the peculiar constructionof the registering mechanism and means for carrying upon the registeringwheels; further in the peculiar construction of the indicatingmechanism; further in a device for coupling operated keys and in thedevice for preventing the simultaneous operation of two or more keys,all as more fully hereinafter described.

In the drawings, Figure 1 is a vertical section through a cash registerembodying my invention. Fig. 2 is a cross section on line a: with thecasing removed and looking to the right in Fig.1. Fig. 3 is a top planview with the casing removed. Fig. 4. is a detached perspective view ofa portion of the rear ends of the keys and showing the key couplinglocked. Fig. 5 is an elevation of the holding up and throwing downmechanism for the tablets. Fig. 6 is asection similar to Fig. l,showingthe registering mechanism partly operated. Fig. 7 is a similar sectionshowing the position of the registering wheels at the end of the upwardstroke of the key. Fig. 8 is an elevation of one of the registeringwheels showing the carrying mechanism, set to carry one. Fig. 9 is asimilar section showing the registering wheels and carrying mechanismreturned to their normal position. Fig. 10 is a cross section throughthe keys, showing the B is a series of keys preferably arranged ingroups of nine keys in a group and numbered respectivevly from 1 to 9.

In the drawings I have shown four groups (Fig. 3), each grouprepresentinga monetary denomination. These keys are all journaled uponthe transverse shaft 0, which is secured at its ends in the casing. Atthe rear end each key has pivoted to it a vertical rod D'which is anindicating actuating rod. Each of these rods is provided at its upperend with a spindle or pin D, which passes through a suitable aperture orslot D in an indicator supporting arm E. The arms E are pivoted upon acommon shaft E, extending transversely across the rear of the machine,and at theirforward ends eachcarries atablet E hearing upon its face afigure corresponding with that upon the finger piece of the key lever,and adapted to be exposed through an aperture E in the front ofthecasing, one aperture being arranged opposite each group of keys.These arms E are of ditterent length, the first one extending only tothe rear tablet, the second one passing under the rear tablet to thesecond tablet, and so on, the last one passing beneath all, beingsecured to the front tablet. Thus, ifthe front tablet is desired to beexposed, supposing it to be a 9 tablet, the operator depressing the keywill lift all the tablets together, but the 9 tablet being in front willbe exposed.

F is a cipher tablet secured upon the arm F, which is pivoted to theshaft E and extending across the top of all the tablets, as plainlyshown in Fig. 1, in such position that it is normally exposed to view,but upon the operation of any key, the corresponding tablet operated bythat key will lift the cipher and carry it away from the aperture E toexpose the operated tablet.

Instead of using the construction shown in Figs. 1 and 2, I may use aconstruction for the tablets such as shown in Figs. 12 and 13, the

change in construct-ion relating to the cipher sign in indicating anynumber of low value, such for instance as 50. With the device aspreviously described, the indication will read 0.50. I desire to use ashield in connection with the cipher signs which will obscure all ciphersigns in the unoperated higher denomi nation in indicating such numbersas that above mentioned .50.

To this end I employ a shield U secured upon an arm U which is pivotedupon the shaft E and extends across the aperture E in front of thecipher sign F, one shield for each denomination. Each shield is providedupon the edge nearest the higher denomination with a hook or finger Uwith which an arm U upon the shield of higher denomination is adapted toengage, as plainlyshownin Fig. 12, all so arranged that if, forinstance, a figure is desired to be indicated in the units column alone,the lifting of the tablet in that group will carry with it the ciphersign and the shield, allowing the shields in all the other groups toremain unoperated.

If a figure is to be indicated in the tens group alone, such as ninetycents, the arm U on the tens shield will engage with the hook U on theunit shield, and raise the unit shield with it so that the cipher signwill be exposed to view.

The mechanism for holding up and throwing down the tablets for eachindication con= sists.of a universal bar a, which is actuated by any keyof any group. This bar in the drawings I have shown as a coupler bar forcoupling together the operated keys of each group. Any other universalbar will accomplish the same result and I do not desire to confinemyself to such a bar as I have shown. To this bar or to the arm 1)thereof is secured a vertically extending rod 0 guided in suitablehearings to near the top of the macl1ine,where it is provided with ahead (1 having an inclined face 6 at its outer end.

fis a latch bar suspended on hangers g in rear of the tablets. Thesehangers are secured to shafts h journaled in stationary hearings in theframe, one for each group of keys and extending beside the tablet rods,as plainly shown in Fig. 7,provided at their outer ends with a latchz'of suitable width to engage beneath the lower edge of any one of thetablets in a group. Each tablet is provided with a shoulder it, havingan inclined face 7L2, as shown in Fig. 5.

Upon the operation of a key its tablet is raised; the inclined face 72,2striking on the under side of the latch i will move it to one side toallow the tablet to be elevated, and as soon as the head has passed, aspring 7' will move the latch bar f, rock the shafts h and cause thelatch 11 to engage beneath the edge of the elevated tablet and hold itin position opposite the slot E The operation of a succeeding key willthrow down the previously operated tablets by means of the head 6striking the arm upon the bell crank lever 7t: and causing that lever toshift the latch barf, rocking theshaft h in such a manner as to carrythe latches i from beneath the tablets to allow such tablets to resumetheir normal position. As soon as the head e has passed the arm of thebell-crank-lever 7c, the latch z' is carried by the spring j into itsoperative position to hold up the tablet-rod carried by the operatedkey. The downward movement of the head ewill rock the bell crank leverin the opposite direction so that it will not strike the bearing Z onthe barfand thus will have no effect upon the latch bar or latches, butwill assume a position ready to throw down all the elevated tablets uponthe succeeding operation of a key.

The bar a is supported upon the ends of the bars I) which slide in thetube at, hinged at the front of the machine. The end of the rod 1) bearsagainst a springn in the rear end of the tube m. This spring acts withits tension to keep the bar a constantly in contact with the cam 0 secured at the sides of the machine in rear of the keys, as plainly shown inFig. 4. The bar a is provided on its front face with grooves 19 adaptedto be engaged by means of the cam o with the notched bearing 1) upon theend of the key, so that upon the operation of two or more keys the bar awill couple them together, being lifted during the first part of itsmotion by the finger g on the keys, and moved into a coupling positionby bearing against the cam o as soon as the keys have been slightlyelevated.

r is a swinging lever having a cam 4- at its lower end adapted to bestruck by the universal bar a in its upward movementto swing theuniversal bar 5 carried by one end of a locking lever s over the fingersq of the unoperated keys, as shown in Fig. 7. As soon as the keys arecoupled together, the operator can release his hold upon all but one ofthem, and by continuing the depression upon one, can indicate andregisterthe value of all the keys together, and by means of theuniversal bar 3 and finger q, "all of the unoperated keys are lockedagainst operation, as soon as the operated keys are coupled, or as soonas a single key is engaged with the coupling bar, the cam r on the lever9" being coincident with the cam 0 which actuates the coupling bar.

To prevent the simultaneous operation of two keys in the same bank, Iuse the following mechanism: Beneath each group of key levers is aseries of slotted plates 25. In this construction which embodies ninekeys for each group, each plate has eight slots in line with eight keys,and one slot slightly out of line with the ninth key. Thus, for the keyif in Fig. 10, the plate 6 is shown as having slots in line with eightkeys, but a slotoutof line with the key '6', and provided with aninclined bearing or cam it directly beneath the key 15. Now upon theoperation of the key t it will strike the inclined bearingtt moving theplate 25 laterally until its slot 10' registers with the slots in theother eight plates and passes down into all the slots, locking any ofthe plates from end movement, and at the same time moving the plate '6so that the slots previously beneath the other keys are moved toone sidethereof. As each one of IEO the plates has a slot out of alignment witha' key, and a lug for actuating that plate upon the depression of itskey, it is evident that when one key has entered the nine slots asdescribed, no other key can be operated because all the plates arelocked against end movement, and each of the eight remaining unoperatedplates with an inclined bearing a thereon, forms a lock or stop for theremaining keys. Thus, I have a device which comprises a series ofplates, each of the plates forming a locking plate for one key, and soconstructed that upon the operation of one key all of those plates arelocked against movement except that one beneath the operated key. Aspring i bearing against the ends of all the plates returns any one ofthem which may be moved laterally to its normal position as soon as thekey is returned.

My registering mechanism is designed to give a totalization of all thesums which have been added in all the banks of keys, and by a mechanismwhich is simple and efficient, com prising but one registering wheel foreach monetary denomination or group of keys.

G, G, G2 and G are four registering indicating wheels having upon theirperipheries suitable numbers from 1 to 9, with a cipher, each wheelrepresenting a single monetary denomination, that is, representingrespectively cents, dimes and dollars, and tens of dollars, if used forregistering the currency of the United States. To each one of thesewheels is secured a registering actuating wheel H., H, H and Hrespectively.

A description of the keys in the units and tens bank will suffice foradescription of all, and I will therefore confine myself to such adescription. Theregistering actuatingwheel H is of sufficient length toextend over all of the keys of the units group, and each key is providedwith an actuating arm I havinga ratchet bar 1' adapted to engage withsaid wheel and turn it proportionate to the value of that key. For thekeys of higher value such as 6, 7, S, and 9, I preferably use twoactuating bars, one similar to I and another J pivoted upon the key infront of the bar I and having corresponding teeth I adapted to actuatethe registerwheelupon the return movement of the key, while the teethupon the bar I are adapted to register during the forward movementthereof. In such case I couple the two bars together, by means of aspring J, which allows the teeth on that bar which is not operating theregistering wheel to slide over the teeth upon the wheel acting as aguide to hold the operating har tightly in contact with the teeth.

K is a spring pawl acting to hold the register wheel in its adjustedposition and prevent its reverse movement.

L is a carrying arm pivoted upon the bar L and arranged in proximity tothe face of the register wheel G. It carries a pawl M engaging with theregister actuating wheel H of the tens group. This arm is provided withan upwardly extending finger M adapted to engage with a spring catch N,which is provided with a shoulder N, forming a stop to hold the arm L inits normal position, and a shoulder N adapted to hold the arm L in itsoperative position, a spring 0 being provided to actuate the arm L and aspring 0 to hold the catch N in engagement with the finger M of the armL.

Pis a cam shaped face upon the arm L, arranged in line with a pin P uponthe inner face of the register wheel of the units group. The parts beingin the position shown in Fig. 9, as the units key completes itsrevolution the pin P will strike the cam shaped face P upon the arm Land carry that arm backward until the finger M engages with the shoulderN upon the catch N, just as the pin P passes out of engagement with thecam shaped face P. This will move the parts into the position shown inFig. 8 carrying the pawl M back one notch upon the register actuatingwheel of the tens group. The parts will remain in this position untilall the keys have returned to their initial position, and as theyapproach this initial position, the latch N is released from the fingerM by means of a connecting bar Q, having a lug Q adapted to strike afinger R upon the opposite end of the latch N, this connecting bar beingsecured to a universal bar S. As soon as this latch is released, thespring 0 will draw the finger M forward until it strikes the shoulder N,which will carry the tens wheel one notch, causing it to carry one.Thus, I obtain my carrying after the keys have completed theiractuation, and the register wheels are at rest, preventing any necessityof complicated mechanism, and insuring a perfect registration of allamounts. At night, the operator has simply to read the total from theregister indicator wheels, as shown in Fig. 2, which gives the sum as$79.30.

It is evident that various modifications of this carrying andregistering mechanism may be employed, and I do not desire to limitmyself to the precise mechanism shown, but

What I claim as my invention is 1.
